Nordic Semiconductor’s new nRF51922 system-on-chip (SoC) is said to be the world’s first multi-protocol SoC solution offering concurrent ANT+ and Bluetooth low energy (LE) wireless communication natively in a single chip.
By bringing together two of the most popular wireless technologies in the ultra-low-power wireless industry today, the new chip means product developers in markets like sport, wellness, healthcare and smartphone appcessories will no longer be forced to choose between one or other of these previously incompatible wireless technologies.
The nRF51922 enables full flexibility in using one or both protocols concurrently in a product, enabling multiprotocol acces-sories and compatibility with ANT+ and Bluetooth Smart Ready hubs. It is drop-in compatible with existing nRF51 series devices, but features Nordic’s brand new S310 SoftDevice that combines the ANT+ and Bluetooth low energy stacks in a single software framework.
The S310 offers the same fully autonomous, secure and event-driven application interface as existing Nordic SoftDevices, which includes a clean separation of protocol stacks and application firmware to simplify firmware development and testing, and maximise operational reliability.
Pin-compatible hardware and a familiar interface on the S310 for existing Nordic S110 (Bluetooth low energy) and S210 (ANT+) SoftDevice users means Nordic customers that already have an nRF51 Series ANT+ or Bluetooth low energy product will be able to keep existing hardware design and firmware unchanged, and only add needed firmware support for the new protocol stack when adopting the nRF51922.
